SAFE transport of hot gases and vapours at temperatures of up to 850°C – this is a problem facing many manufacturers of components for the process industry. The smart choice for the solution is austenitic stainless steel 1.4550/347H. To meet the increasing demand, Ugitech has added UGI® 4550 to its broad stainless portfolio, and is one of only three suppliers in Europe. Steam lines, superheater tubes and exhaust systems in reciprocating engines and gas turbines are classic applications for Ugitech’s UGI 4550. The addition of Niobium makes the finished steel grades a well-adapted solution for temperature ranges between 425°C and 850°C. Ugitech leads from the front in Europe

Compared to most austenitic materials, UGI 4550 inhibits the formation of chromium carbide precipitates at the grain boundaries and thus stops intergranular corrosion. The stainless product is optimum for parts for which treatment of the material after welding is not feasible, such as expansion joints and equipment for chemical processing at high temperatures. UGI 4550 is also readily formed at room temperature and is very easy to weld. This means no hot cracking after welding. Good creep resistance (resilience against temperature-dependent deformation) and resistance to atmospheric corrosion and oxidation at high temperatures further increase process reliability. Ugitech offers UGI 4550 in a wide range of dimensions: from steel bar with a diameter of 130mm to ultrafine 16µm in diameter. The steel product is annealed or cold drawn to the required mechanical properties. The minimum order quantity at Ugitech is one ton for drawn steel bar and even lower for drawn wire. Ugitech is always able to deliver rapidly because the steel mill is equipped with 40t melting furnaces. Ugitech SA – France Website : www.ugitech.com
